• >SOLVED My FFMPEG throws me unexpected errors while writing a Thumbnail to the songs

  22 février 2019, par Harmonised7

  My issue was that my songs already had a thumbnail. Solution to overwrite thumbnail below !

  I am using Node to execute my ffmpeg. I use this wrapper :

  https://www.npmjs.com/package/ffmpeg

  Everything was fine when I was using smaller versions of the thumbnails provided by Youtube, but when I attempted the HD ones, it suddenly started giving me an error. I’ve tried -pix_fmt yuv422p and Many other pixel formats, but nothing helped. Though ONE out of 100+ songs did tag successfully.

  here is my code :

  downloadTags(tags.thumbnail, `./thumbnails/${tags.title}.jpg`).then(thumbnail =>
  
                      {
  
                          video.addCommand('-i', `"${thumbnail}"`);
  
                          video.addCommand('-map', '0');
  
                          video.addCommand('-map', '1');
  
                          video.addCommand('-c', 'copy');
  
                          video.addCommand('-c:v:1', 'png');
  
                          video.addCommand('-disposition:v:0', 'attached_pic');
  
                          if(tags.title)
  
                              video.addCommand('-metadata', `title="${tags.title}"`);
  
                          if(tags.artist)
  
                              video.addCommand('-metadata', `artist="${tags.artist}"`);
  
                          if(tags.id)
  
                              video.addCommand('-metadata', `comment="https://www.youtube.com/watch?v=${tags.id}"`);
  
                          video.addCommand('-pix_fmt', `yuv422p`);
  
  
  
  
  
                          var output = 'downloaded'
  
                          if (outFolder)
  
                          {
  
                              output = outFolder;
  
                              if(!fs.existsSync(output)) fs.mkdirSync(output);
  
                          }
  
  
  
                          video.save(`"./${output}/${tags.title}.${tags.format}"`, function (error, file) 
  
                          {
  
                              if (error)
  
                              {
  
                                  resolve(error);
  
                                  return
  
                              }
  
                              try
  
                              {
  
                                  fs.unlinkSync(song);
  
                              }
  
                              catch(err)
  
                              {
  
                                  console.log(err.code);
  
                              }
  
                              resolve();
  
  
  
                          });
  
                      });
  
  
  
                  }

  and here is my error :

  Any suggestions ? Getting really desperate at this point...
